QED Naval Secures Canadian Patent for Subhub

QED Naval has been granted Canadian patent application for the Subhub tidal platform.

The application covers submersible apparatus and methods of installing anchoring equipment and refers to the hydrodynamic impacts of the Subhub.

With this award of patent and the validation data from the technical demonstrator, QED Naval are looking to exploit the Subhub technology and market in Canada, the company said.

The Subhub platform is said to be a fully integrated platform which encapsulates everything required to operate seabed mounted tidal turbines invisibly, offering the industry reliable deployment over a wide range of weather conditions.

According to QED Naval, the Subhub is suitable for any type of turbine, and can be modified to capture the benefits of both horizontal axis, and vertical axis turbines, while the platform’s ballasting methods can work equally well with wave turbines as well.
